Poking your fingers into a computer case will result in cuts. The gods of computer repair demand blood sacrifice.

The last 10% of the job will take 90% of the time/budget.

 

 

Fixing it for you: The last 20% of the job will take 80% of the time/budget. (Pareto Principle)

 

Sorry, freitasm: Sideface is correct for Technology projects.

The Pareto Principle is far too generous in its application to The Wonderful World of ICT
For what it's worth, I think that's largely due to the tendency to leave the hard bits until last, then the 'last 10%' ends up consuming 90% of the effort ...

1101:

 no one will ever need more than 640k of ram

That wasn't a law and wasn't immutable.

Also Bill Gates never said that.

But still he denies saying that 640Kb RAM was what people needed and making it a limit. It was never a limit per se as we all know (HIMEM.SYS and other memory managers were from 286 and 386 processors and up).
